Consumer Reports has laid its hands on the 2015 Cadillac ELR plug-in hybrid and spent ten days testing out the high-end hybrid vehicle. The publication says that after ten days of driving the car, it's hard to categorize.

While the Chevrolet Volt costs around $34,000 before a $7,500 federal tax credit, the Cadillac ELR with the same drivetrain starts at $75,000. Consumer Reports says that the massive sticker price for the ELR doesn’t add up.

The publication says that the rear seats in the ELR are much tighter than the rear seats in the Volt, which were already nearly too small for adults. Consumer Reports does say that the ELR is much nicer to drive than the Volt, and that you can barely hear the gas engine when it turns on.

The interior is also "sumptuous" and beautifully finished according to the publication. In the end, Consumer Reports felt that the car was "rather ordinary" and lacks the "zip" you expect in a high-end coupe. The publication says they would rather be rolling around in the roomier and better performing Tesla Model S, granted the Model S can be much more expensive than the ELR and is hindered by the range of its battery pack and reliance on recharging.

The ELR can go for 35 miles thanks to its 16.5 kWh battery and has an 84hp gas engine to assist on longer trips.
